Disclosed are branched polyphosphonates produced using a polycondensation process, that result in polyphosphonates having a Tof at least 100&#xb0; C., and which can be further processed to have improved hydrolytic stability compared to other polyphosphonates. The method and polyphosphonate compositions may be made from readily available starting materials providing lower cost fire retardant materials. Also disclosed are polymer compositions that comprise these branched polyphosphonates and at least one other polymer, wherein the resulting polymer compositions exhibit flame retardant properties.

Branched polyphosphonates

Disclosed are branched polyphosphonates produced via a superior transesterification process, and methods related thereto. These branched polyphosphonates exhibit a unique and advantageous combination of properties, such as outstanding fire resistance, improved heat stability, improved toughness, and superior processing characteristics. Also disclosed are polymer compositions that comprise these branched polyphosphonates and at least one other polymer, wherein the resulting polymer compositions exhibit flame retardant properties. Further disclosed are articles of manufacture produced from these polymers, such as fibers, films, coated substrates, moldings, foams, fiber-reinforced articles, or any combination thereof; these articles may be coated with a moisture barrier to enhance their moisture resistance properties.

Branched polyphosphonates that exhibit an advantageous combination of properties, and methods related thereto

Disclosed are coatings, films, and articles of manufacture comprising or derived from compositions that are produced by a method for exchanging solvent in a mixture that includes water and an optionally substituted thiophene. Also disclosed are methods for making and using said coatings, films, and articles of manufacture, including electro-optical implementations.

Compositions produced by solvent exchange methods and articles of manufacture comprising same
